-To all whom z't may concern:

Be it known that I, JEssEA.' B. SMITH, a citizen of the United States, residing in Stamford, in the county of F airfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following a specification. f

The invention ,relates to typewritmg inachines. More particularly, the invention relates to so-called billing machines in which' provision vis made for feedinga Succession of bill' orvother form-sections in a continuous web, and in a plurality of plies, to the laten and in which carbon-sheets carried P n v on one or more rolls of a carbon carrier, are interleaved with the web-plies; the. carbonearrier being, mounted 1n a runway on a table attached to the platen-carriage to have line feed movement with the web toward the platen, and to be moved rearward on the table for clearing the carbons'of the leading written forni-sections and bringing the carvbons into interleavement with succeeding Jorni-sections, at the completion of the typewriting,r on the leading form-sections. A machine of this general class is shown in United States Letters Patent to lVe-rnery and Smith, No.. 1,132,055, dated March 16, 1915. In the machine therein shown, the car'- lionfsheets are individual sheets secured at their rear ends to blades on the carbon-car rier. and are. of alimited and predetermined length, forward from the blades, sutlicient to cover the leading form-sections of the worksheet plies, and to be gripped with the latter to the platen when the carbon-carrier is in its rearward position preliminary to `commencing` writing on the leading form-seotions. Carbon-sheets necessarily become worn in use, and new sheets or fresh carbon-areas of the same sheets must be substituted from time to time for the worn ones. The interleavement of individual carbon-sheets with the plies of a multiple work-sheet web, and the attachment of such sheets to a carbonearrier, involve time and inconvenience. Rolls of carbon,- aper have'therefore been substituted on t e carbon-carrier for the relatively short individual sheets previously used. Rotary movement of such a roll pervthat is to say, unless-and avoid the necessity lmits the desired length of sheet to be 11nl bon-carrier when the platen has line-space` movement, and so that rearward throw of the carbon-carrier will shifty the interleaved portion of the carbon-sheet rearwardY along the web-plies. y tion' of the carbon-sheet becomes worn, th'el roll may .beunlocke'd and the carbon-sheet drawn forward sutliciently for detachment therefrom of the leading, worn, part, and for replacement of such part by a fresh length nnwound from the roll. Obviously, in such yuse of a carbon-roll, the operations otl attaching carbon-sheets to the carbon- 'carrier, and of interleaving the same with web-plies, maybe done once and for all,-

until the roll is exhausted or is to be replaced.

The web-plies have, however, heretoforev been fed through the carbon-carrier, usually from the rear thereof; and whereas, as in the Werneryand Smith patent, theweb-plies maybe compactly handled and easily fed and interleaved at the carbon-carrier with individual carbon-sheets held by blades, on

lVlien such interleaved poi,

the carrier, it has not been found economical as to space required, or entirely satisfactory as to the feedthereof, web-plies between the carbon-rolls for yinterleavement with the carbonfsheets. To of feeding the web-plies between the carbon-rolls, the latter have been set on the carbon-carrier to the side of the path ofthe web-'plies through the carrier, and the interleavement has been effected forward of the rolls. This expedient, however, has involved a Widening, and, heretofore, an increase, in the weight, of the carrier, and, because of such additional weight, has heretofore thrown an additional burden on the platen-carriage. ot'ttimes resulting in sluggish or` unreliable letter-feed action of the latter or in disadvantages arising from the increased'inertia of the platen-carriage.

An object of the present invention'is the provision of means, and an arrangement of to pass the .As to this feature thereof, the inventionv parts, whereby a single carbon-carrying roll or holder may be made to serve for a plurality of superposed carbon-webs; and of means for separating and guiding crosswise into the path of the work-sheet web, and into proper planes for interleavement with the plies of the work-sheet web, the several carbon-webs delivered by such single roll; thus eliminating much equipment and weight heretofore incident to the use of a Separate roll for each carbon-web. Where the worksheet web' is a fan-fold of more than two plies, or if, for other reasons, desired, there may be a roll at each side of the carbon-carrier, each roll bearing a plurality of carbonwebs.

A feature of the invention isa simple and novel style andmounting of bars for turning, toward the platen, webs brought laterally or crosswise into position behind the platen; such that the turning bars maybe readily placed and removed, and may be automatically and'securely locked in place.

may, as hereinafter shown, be used on the carbon-carrier for lturning carbon-webs, or be used elsewhere for turning work-sheet web-plies. n

A further feature of the invention is the provision, in conjunction with a turning bar for a carbon-web, of a blade for Split-- ting apart the plies of a fan-fold work-sheet web with which the carbon is interleaved; the splitter being adapted to be made unitary with the turning-bar and detachable therefrom, and the two together unitary with a bar for guiding thecarbon into its proper/plane for interleavement with the work-web plies. Otherfeatures and advantages will hereinafter appear.

The platen 10, by means of its aiile 11, isy

' journaled in side plates 12 of a platen-frame,

pivoted at 13 on the side plates 14 of the platen-carriage,

to swing up and down be tween its operative position and a carbonreleasing position.v The side plates 12 of the platen-frame have rearward extensions 15,

which, when the platen is in operative posiact, to lockthe'swin lng frame, asthe latter comes to rest upon t e shaft 16.

i An extension on the left-hand hook 17 serves as a finger-piece, whereby to rock the hooks and shaft 16 backward to unloclp the frame 12 when the latter is Vto be lifted to carbon-releasing position. The frame 12 carries a table 22 over which the leading form-'sections of the web are fed; and the table 22 carries a gege-arm 23 and gage. 24, to which latter the leading edges of the web are drawn when the platen-frame is in car-- It is, furthermore, a rockbon-releasing position, or determining the lengths of web to be severed.

'The platen-carriage is provided with the usual rear paper-table and apron 25 for guiding the webs and carbons down around and to the front of the platen, and with the usual front and rear pressure-rolls 26 and 27, respectively. The webs are led from the carbon-carrier table,.over and around the shaft 16 down to the platen, as shown in- Figure 2. The platen-carriage is supported for movements in letter-feed and return div rections on the main frametnot shown) of the machine. n

The carbon-carrier table is a substantially rectangular frame, the front cross-piece 34 of whlch is fixed toand supported by brackets 35 on a bar 36, which formspart of the platen-carriage and connects lthe side plates of the latter. The carbon-carrier table is supported at its rear'on a rail (not shown) for movement with the platen-carriage in letter-feed and return directions.

Rails 42, extending lengthwise of the side reaches 37 of the carbon-carrier table, provide a runwa on which the carbon-carrier table is mova le, with the carbons, forward step by step as the; platen has its line-space movements, and on which the carbon-carrier maybe thrown rearward a predetermined distance to withdraw the carbons from the leading form-sections of the web after typing on each'sect-ions has been completed and the platen-frame thrown to carbon-releasing position. The carbon-carrier comprises a rectangular skeleton plate 43, see Figures 1, 2 and 5, having journaled on the under side thereof rollers 44 which are grooved to receive the rails 42 and guide the carrier therealong. An arm 45 secured by screws 46 to the left-hand side of the carrier-plate 43 extends forward and terminates in a lingerpiece 47 by means of which the operator may throw back the carrier to shift the carbons along the web.

`The work-sheets, in the form of endless superposed webs 48, 4S", 48, 48d and 48e, are led onto the carbon-carrier table, at the rear thereof, and thence forwardly through the carbon-carrier (where, as presently to be described, they are interleaved with the carbons), to the rear of the platen-carriage, down over the paper-table and apron 25, around the platen, across thevprinting line, and up over the table 22, as shown in Figure 2. -Thus far the structure described is not substantially different from that shown in the above-mentioned United States Letters Patent to Vernery and Smith, No. 1,132,055, dated March 16, 1915, to which reference may be made for a fuller or more detailed understanding of the operations above mentioned.

In the present invention, the carbons 50, in the form of endless sheets 50, 50h, 5()c and 50, are led from rolls 51 and 52 on the sides of the carbon-carrier. The carbons 50a and 5()c are wound as superposed webs on the roll 51 at the left-hand side of the carbon-carrier, and the carbons 5()b and 50d a's superposed webs on the roll 52 at the right-hand side of the carboncarrier. The axles 53 and 54 of the rolls 51 and 52 are set parallel t0 the sides of the carbon-carrier, so that the carbone may be led therefrom transversely to and over the carbon-carrier table. Bosses 54fL on the carbon-carrier plate 43 serve as bearings in which the axles of the rolls 51 and 52 are journaled for rotary movement. The forward bosses 54a on each side of the carbon-carrier have arms 55 integral therewith; each 'of these arms having pvoted thereto, at 55, a pawl or detent 56 forv engz-xgement with a toothed wheel or rack 57, fast to the corresponding roll 51 or 52, to lock the roll against rotation. A 'spring-detent 58 (see Figures 1 and 3), on each pawl 56, by engagement with the corresponding arm 55 serves to hold the pawl in its' ineffective, Figure 3, position, or in its effective position, in which latter position the pawl engages the teeth on the rack 57. Pins 59 on the arms 55 serve'as stops to determine the ineffective positions of the pawls 56, Finger-pieces 60 on the pawls serve as means for throwing the saine into and away from the racks 57. f

It will be understood that, at the line-feed .movements of the platen, the carbon-sheets are not unwound from the rolls. Upon linefeed movement of the platen, as hereinafter explained, the carbon-carrier advances toward the platen.

bon-sheet having been drawn from its roll, the roll is locked against rotary-'movement by a detent 56. It islonly when the length of carbon-sheet in use has become worn that the roll is released to draw off a fresh length therefrom. This withdrawal may be accomplished by the line-feed movement of the platen if it is so desired.

The carbon-sheets being led over the carl boncarrier table, and onto the carbon-car'` rier at right angles to the feed of the webplies 4S, to the platen, it becomes necessary to provide means on the carbon-carrier for turning the carbon-sheets at right angles, sov

that, as finally interleaved with the web-plies 48, they may move with the latter to the platen. This turning of the carbon-sheets is effected by means of a series of turning bars 61, numbered also, respectively, 61a, 61", 61c and 61d. The bars 61a and 61, which take care of the carbon-sheets 50l and 50c, respectively, from the left-hand side of the table, extend diagonally from the rearward leftli and side of the carrier to the forward righthand side of the carrier, and the turning bars 61b and 61d, which take care ofthe carbon-sheets 501J and 50d, from the righthand side of the table, extend diagonally from the`rearward right-hand side of the carrier to the forward `left-hand side of the carrier, as shown in Figure 1. Each turning bar 61 has, unitary therewith, a bar 62, which extends forwardly `vand rearwardly, parallel to the sides of the carbon-carrier, and which, as shown in Figure 3, have the function of directing and guiding the carbon-sheet from its roll, into its'proper plane for interleavement with the web-plies 48. The combined 'turning bars 61 and guidebars 62 for the several carbon-sheets are supported in grooves 63 in posts 64, of which latter there is one on each corner of the carbon-carrier.- Each guide-bar 62 has at its front and rrear end a finger 65 adapted t0 be set in one of the grooves of the adjacent post 64. The bar 61a for the lowermost carbon'- sheet 50E*v is supported in the lowermost groove 63 of the. front and rear left-hand post 64. The bar 61bfor the carbon-sheet 50" is set and spaced aboveithe bar 61*JL in the groove second from the bottom of the front and right-hand posts 64. The bar 61c for the carbon 50, is set and spaced above the bar 61b in the third from the bottom groove 63 of the left-hand posts 64. The bar 61d for the carbon 50l is set and spaced above 'the bar 61c in the fourth from the bottom groove 63 of the right-hand -posts 64. The bars, therefore, as to the posts 64 on the right and left hand sides, are alternated with each other, that is tosay, 'on each side of the carbon-carrier, are set in every second groove. It, there fore, follows that the intermediate or un- A sufficient length oftcaroccupied grooves on each post 64 might be'130 fouling or being fouled by the carbon-sheets,

when the latter are drawn olf their rolls at right angles to the path of the web-plies. rlhe guide-bars 62, in turning the carbons into planes-parallel to the web-plies, correct any angular dip of the carbon-sheets at thel carbon-carrier which would cause they carbons and the web-plies 48 to foul each othei.

For holding the combined turning and guide members 61-62 against displacement in their own planes, the hars 62 at their forward and rearward ends are provided with yokes to embrace the posts 64. The yoke,

. at the forward end of each bar 62, comprises yof a finger66 for-abutment with the inner fare, of the corresponding post 64, and a linger 67, offset forward' from the finger 65, iullal'itled to-abut the outer ,face of the corresponding post. In setting this forward yokeonto its post, the bar is first set at a slight angle to its final coirect position, and is then given a combined angular and forwardfii'iovement to bring the yoke into the Figure l-position on the post. During this movement, a finger 68, forming one branch oftlieyoke at the rear ofthe bar 62, is brought'against the inner faceof the rear post 64, and a spring- 'detent having a finger 69, which forms the other branch of. the rear yoke, is snapped over the outer face of the rear post. This s riiiff-detent is shown as com risin an arm- 70 pivotedat 71 to the rearward bar 62. A spring 72 fixed at 73 to the bar 62 hears against the forward edge of the detent arm 7 0 and urges the latter rearward around its pivot; the rearward or locking position being determined by a stop-pin 74 on the bar 62. The action of the detent is automatic; and to this end, the nose of the ,detent is curved as at 75 to cam the deteiit rearward as the bar is swung into place, so as to permit the finger 69 to pass the post, for ultimate engagement with the outerface there- In the interleaving of the carbons with the webplics, the lower web 48 is drawn forward so that its leading end is forward of the carbon-carrier. With the carbonrolls 51 and 52 unlocked, a length of the lower carbon 50*1 is drawn crosswise over its y .turning bar 6ln and then turned around and` brought forward under its turning bar. The lower turning bar is thei. locked in place. The next higher web L18b is then drawn over the lower carbon 50 and carbon-turning bar 61a to a ositionforward of the carbon-carrier; andJ the successively higher carbons 50 and webs 48 set in the same manner. After the upper web has been positioned over the upper carbon, and the carbon-rolls 51 and 52, being still unlocked, the webs' and the carbons are seized and drawn forward to the position for printing 4on theJeading web-forni'. The carbon-rolls are then locked, and the carbon-carrier given a rearward throw sufficient to draw the leading ends of the cai-bons slightly rearward of the leadingl -throw deterii'iined by the length of the formsections. i rllie operation of the "typewritrig .machine mayv then be as explained in thc Ve'rnery and Smith patent, hereinbefore referred to. The length of the carbon in use having however become worn the carbon-v rolls are unlocked, the carbons drawn foin ward a distance sufficient to provide fresh printing surfaces, and the worn length of the caibons detached. i

Vhere the work-sheet web-plies 48 are in the forni of a fan-fold, it isoften desirable, as hereinbefore mentioned, to split the plies of the fan-fold apart on the lines of the folds thereof, at the carbon-carrier, by the movement of the carbon-carrier rearward as the latter is operated to shift the cai-bons from the leading ty ewritten form-sections of the web-plies. Al of the plies of the fan.- fold may thus be split apart, or, the fan-fold may temporarily be left intact except for the upper ply thereof, which carries the forni'- sections for outside distribution.`

Iii the present invention, the turning bars, or, if desired, only the u per turning bar, 61, may be ein loyed to e ect such splitting of the web-p ies. For this purpose, the turning bar 61 (see Figures l and 6), in addition to having a guide-bar 62 unitary therewith, has also a forward cross-reach 76 which forms a rigid triangle with the bars 61 and 62.' Projecting forward from the ci'oss-reach 76 is an arm 77, which is offset laterally at 78. Onto the offset 78 is adapted to be slid a piece 79. Downward and inward-turned ears 80 -on the piece 79 forni a slideway for the latter on the offset 78, and, besidey serving to hold the slide to the offset 78, determine the home position of the slide by abutment of one of the end ears 80 with the forwardly-extending arm 77. The slide 7 9' on its distal end carries a blade or slitter 81 which projects laterally beyond the side edge of the fan-folded work-piece, so that,

das the blade 81 is carried rearward with the turning bar 61 and carbon-carrier, it slits the fan-fold for a distance determined by the rearward throw of the carbon-carrier.

NEO

-may be provided.

An offset 82 on the blade-carrier 79 brings the blade into the plane of the turning bar 61.

For turning the platen in line-'space and reverse directions, stub-shafts 83 are journaled in the side plates 14 of the platencarriage., These shafts have the usualha-ndwheels 84; and, at their inner ends, have gears 85' fast thereto. The platen-axle 11 has also fast, to each end'thereof, a gear 86. The gears 85y and 86, at each end of the platen, both mesh with a gear 88 on the axis 13 around which the platen'is swung` from operative to carbon-releasing position. `By means of the hand-wheels 84 the platen may, therefore, be rotated in either position to which it may be swung. lAlso fast to the left-hand stub-'shaft is a line-space ratchetwheel (not shown); and, for'y turning the ratchet-wheel to effect line-space-feed of the platen through the gears 85, 86 and 88, any well-known form` of line-space mechanism Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used without others.
